Ok the back of the scope base not the scope is loose i can make it wiggle when i touch it the front of the base is solid. so the rear of the base next the the chamber of the barrel is slightly loose, it has very little play but it has play. it usually comes to reset exactly where it should be but i fear this could be throwing my shot off. although this is a slug gun and i do not need it to accurate out to 300 yds. so it may not make any difference. anyhow the big problem is the eye relief.
